would surely ask

well i did not understand what u mean actually
you can tap into the reserve power stored in the battery

please elaborate sir

bike has two power source... alternator(AC) and battery(DC)... but both are independent

if you convert the AC power from alternator to DC
and connect to battery!!!

thats it... no from that battery terminal you can get the DC power from alternator(instantaneous) as well as from battery(reserve power)

Ok let us consider 2 situations -

1. Bike is at idle - Now the alternator makes 60W (say)(W is Watt, unit of power). But load on it is 80W (headlight, console, etc). Now, in this case load is more than supply by 20W. If we do not use the battery, the light will dim. This is why the headlight dims at idle.

2. Bike is at 4k rpm - Now alternator makes its full rated power 110W (say). Now load is 80W only. So headlight etc runs at full capacity. Note that 30W is wasted.

Now if we use a battery, at idle it can supply the deficit power (20W) to the headlight. And it gets charged at higher rpm with the surplus power (30W).
End result - your headlight never dims!

Thus the battery covers up for the alternator disadvantage - it makes greater power at higher rpm and conversely lower power at lower rpm. This is the advantage of an all DC wiring.

3 (So where do u expect the fuel knob to be?

On top of the tank?

.... Its ok... I like the way they have presented the knob... Neatly packed.... Once again far better than the HH and Bajaj bikes)

4 (You wont put this point if u own a GS

.... When i test rode this bike i felt it heavy... But now... I zip zap thru traffic as if i am riding a splendour

)
5(Most of the 150cc bike segment has got high pillion seats....Even xtreme and apache have high pillion seats.... This bike is not for oldies

)

8(I love the handling in this bike

.... No way i can quote it as a negative point)

I ll put forward the points 1, 6 and 7 for sure

bubbly bubbly

i was talking everything on comparative basis

aur fz aur 200 picture mein kaha se aye?
we are talking about 150CC COMMUTERS

COMPARATIVE is the word my friend

and the high pillion seat is way high,,,,,, that to for a commuter bike

i was telling that if there was a monoshock,,,,,,, you would have got much more better than what i said........ rather a suggestion than calling it a mistake,,,,,,,,, when did i call the handling bad or something

bas no more talks on this,,,,,,
as usual m misinterpreted

Nope not exactly independent. The primary source is AC. It is split into two lines - one line supplies the headlight (AC) and another line is converted to DC by the regulator unit and charges the battery. Rest is correct.

Well I can not help you without any circuit diagram!

oh... i thought there seperate coil to charge the battery...
thank you for correcting me

strange!

try the workshop manual
request the sc guys to take xerox or print out of the electrical circuit diagram for u
obviously from a service center where you do not give ur bike

@ mr abhijeet and mr ssivakumar
thanks a lot for your answers

but as told .......... if in any case the earthing fails or there is some problem
the unbelievable voltage might burn up our ass

is there a safety measure involved here?

u got guts to believe the risk is worth taking

No no no! I was talking of the overall situation. If you want to get real deep into the matter this is how it works. There are many coils. I am talking about my P150 here. GS150R will be similar. There are 3 coils for charging the battery. These 3 coils generate 3 phase AC which is regulated and then rectified by a 3 phase bridge rectifier and finally fed to the battery. There is another coil. This coil output is also regulated and drives the headlight, tail light and instrumentation lights only. Yet another coil powers the CDI unit only. Total 5 coils.

Edit - When I said not exactly independent I meant that all the 4 coils except the CDI coil is regulated using the same regulator unit. Also output from all the coils depends on the speed of rotation of the same magnet only.

i really cant understand

why shouldn't i ask that service center to which i am giving my bike... this might be a very silly question to all

Oh... 3 phase

If the earthing of the stock regulator fails, it will result in everything going for a toss.

Earthing is very important. But the custom rectifier which I am using on my bike is not a critical item like that. It will not fail that way!

I think he meant that if the service center where you service your bike knows that you are modifying your bike electricals, he may refuse warranty in case of any future problems.

because obviously a person with a normal regular IQ level might understand that you are asking the diagram for some reason
if he is a good person..... would not meddle
but if he is some dumb,,,,,,, he would obviously check out ur electricals next time and it might screw ur warranty

thats it
play safe mate
